Explain the different Types of Microcontrollers.

Microcontrollers are divided into various categories based on memory, architecture, bits and instruction sets. Following is the list of their types Bit.

Based on bit configuration, the microcontroller is further divided into three categories.

8-bit microcontroller: This type of microcontroller is used to execute arithmetic and logical operations like addition, subtraction, multiplication division, etc. For example, inte1 8031 and 8051 are 8 bits microcontroller.

16-bit microcontroller: This type of microcontroller is used to perform arithmetic and logical operations where higher accuracy and performance is required. For example, Intel 8096 is a 16-bit microcontroller.

32-bit microcontroller: This type of microcontroller is generally used in automatically controlled appliances like automatic operational machines, medical appliances, etc.

Memory: Based on the memory configuration, the microcontroller is further divided into two categories.

External memory microcontroller: This type of microcontroller is designed in such a way that they do not have a program memory on the chip. Hence it is named as external memory microcontroller. For example: Inte1 8031 microcontroller.

Embedded memory microcontroller: This type of microcontroller is designed in such a way that the microcontroller has all programs and data memory, counters and timers, interrupts, I/O ports are embedded on the chip. For example: Intel 8051 microcontroller.

Instruction Set: Based on the instruction set configuration the microcontroller is further divided into two categories.

CISC: CISC stands for complex instruction set computer. It allows the user to insert a single instruction as an alternative to many simple instructions.

RISC: RISC stands for Reduced Instruction Set Computers. It reduces the operational time by shortening the clock cycle per instruction.
